The posting of referral links is and has for a long time been against the rules.

The PS3ISO's Official Forum Rules. <Read This First>
Links that are not allowed:
-Pay per click sites(link bucks)
-Sites that require you to do a survey to get the links.
-Links to a file host that contains no downloads or the poster gets points/cash for them (this is considered spam)
-Links to porn are not tolerated.
-Links to other sites like ours or any site with a forum. (Not our sister sites)
This is just one of the many rules that is broken on a daily basis and it is getting sickening.
